Sanding sugar, for sprinkling (Sanding sugar is clear and sparkly and its extra-large crystals will not melt in the oven. It comes in different colors, too.)

Directions

Preheat oven to 350 degrees. Sift flour, baking soda, and salt into a bowl; set aside.

Put sugars and lemon zest in the bowl of an electric mixer fitted with the paddle attachment. Mix on medium speed 30 seconds. Add butter; mix until pale and fluffy, about 1 minute. Mix in eggs, 1 at a time, and then the lemon juice. Reduce speed; gradually add flour mixture, and mix until just combined.

Bake cookies until golden, about 15 minutes. Let cool on sheets on wire racks for 5 minutes. Transfer cookies to racks using a spatula; let cool completely. Cookies can be stored in an airtight container at room temperature up to 3 days.
